RICHARD M. FINN, OF MILL VALLEY. CALIFORNIA, ASSIGNOR TO JOHN FINN METAL WO'RKS, OF SAN FRANCISCO, CALIFORNIA, A CORPORATION OF CALIFORNIA.
METHOD FOR vGALVANIZING': CYLINDRICAL BODIES.
Application filed November 15, 1923.
To all whom it may conaem Be it known that I, RIoHAiu) M. FINN, a citizen of the United States, and a resident of Mill Valley, Marin County, State of California, have invented new and useful Improvements in Methods for Galvanizing Cylindrioal Bodies, of which the following is a specification.
M v invention is particularly upplicable to the securing of a Smooth homogenous galvanized coating of even thickness on cyli'ndrical or substantially ,cylindrical articles.
My invention is applicable to Secure 'a perfect galvanized surface, on cylindrical bodies and particularly on the screw threaded or machined4 surfaces of cylindrical bodies as bolts, rods, pipes and the like after they have been dipped in the galvanizing bath.
These objects I accomplish by spinning the cylindrical body, while the coating is still in the molten state, Iabout its own axis as a center of rotation, whereby the Centrifugal force generated in the coating material on the periphery overcomes the cohesive forces within the material, and causes any' superfluous material to be thrown' ofl', thus lcaving an even skin thickness of the coatling' material adhering to the cylindrical surface.
By my invention I am able to remove the superfiuous galvanizing material from the surface of 'cylindri'cal objects as bolts, rods,
and the like, leaving the adhering galvanizing smooth and of equal thickness Withthe screw threads or other interstices thoroughly cleaned of superfluous coating, whereby the surface contour of the original article is retained with a great degree of accuracy.
4 By referring to the accompanyin-g drawing, my invention will be understood. In the drawing, Figure 1 is a side view of one form of apparatusfor practising my inven- Serial No. 674,850. 0
tion. paratus of Figure 1`.
Throughout the figures similar numerals refer to identical parts.
The numeral 1 indicates a hot cylinclrical body which has been galvanized in the confl -ventional way, and on the surface of which the galvanizing material is still in the plastic or molten state. A rotating apparatus comprising a rotating head 2, and an encased motor 3 is energized as by compressed air through the hose, et. At 7 is a guide of cone Shape and into which one end of the body 1 rests and the head 2 grips the other end of the body in any conventionalway and forces its. rotation.
The h'andles 5, 6 may be grasped to actuate the compressed air motor and rotate the body 1 thereby causing the excess material to be thrown ofl' by vcentrifugal force as the body rotates about its axis.
Figure 2, is a plan view of the ap- Other means may be employed to rotate o object between end supports` on its cylindrical axis While said material is still plastic. 2. The method of galvanizing a substantially cylindrical body which consists in -dipping said body in a hot galvanizing bath and thereafter while hot and before the coating has hardened spinning said body on its cylindrical axis between end supports whereby the superfiuous coatiug is thrown ofl' by centrifugal force.
